Detailed Implementation

[0021] The present invention will be further described in detail below with reference to the accompanying drawings.

[0022] like Figure 1-3As shown, this is a desktop small press disclosed in this technical solution, including a base plate 1, a top plate 2 at the upper end of the base plate 1, and the base plate 1 and the top plate 2 are connected by a support leg 3.

[0023] The top plate 2 is equipped with a touch screen 4, and an electrical box 5 is located on one side of the touch screen 4. The electrical box 5 has a built-in PLC. A cylinder 6 is installed at the lower end of the top plate 2. The output end of the cylinder 6 is vertically downward. The output end of the cylinder 6 is connected to a quick-release assembly 7. A start switch 8 is located on one side of the support leg 3. The start switch 8, the touch screen 4, the PLC and the cylinder 6 are electrically connected.

[0024] A positioning structure is provided on the base plate 1, and the lower mold plate 9 is mounted on the base plate 1 through the positioning structure. The positioning structure here can be several positioning holes, and the bottom of the lower mold plate 9 is provided with positioning pins (not shown in the figure), and the two cooperate with each other. Other structures can also be set, as long as they can be used to fix the lower mold plate 9.

[0025] The quick-release assembly 7 includes: a fixing plate 71 for connecting to the output end of the cylinder 6; two connecting rods 72 are fixedly connected to the lower side of the fixing plate 71; a fixing claw 73 is hinged to the end of the connecting rod 72 away from the fixing plate 71; a rotating pin 74 is inserted through one side of the fixing claw 73; and the through hole 75 is arc-shaped and can be used to rotate the fixing claw 73.

[0026] One side of the fixing claw 73 is arc-shaped, and a locking rod 76 is abutted against one side of the fixing claw 73. The arc surface of the locking rod 76 can fit against the arc surface of the fixing claw 73.

[0027] The clamping rod 76 has a structure with cylindrical ends and a tapered middle section. The radius of the cylindrical section is larger than the maximum radius of the tapered section. A spring 77 is fitted onto one end of the cylindrical section, with one end of the spring 77 abutting against the fixing claw 73. A push plate 78 is provided at the cylindrical end with the spring 77. When the spring 77 is not subjected to additional external force, the tapered section allows the two fixing claws 73 to clamp the workpiece. Pushing the push plate 78 can compress the spring 77, causing the clamping rod 76 to translate. Due to the change in the radius of the contact surface between the tapered section and the fixing claws 73, the fixing claws 73 can be released.

[0028] The press can be started with a single-handed flick of the switch, and the equipment will enter automatic operation mode, freeing the operator's hands so that they can turn to other work, thereby significantly improving overall work efficiency.

[0029] Furthermore, several guide rods 10 are installed on the base plate 1, and the quick-release assembly 7 is also connected to a pressing plate 11. The guide rods 10 pass through the pressing plate 11, and the top ends of the guide rods 10 are connected to the top plate 2. The guide rods 10 are used to limit the pressing plate 11 in the vertical direction.

[0030] In a preferred embodiment, this invention can be further configured as follows: a light grating (not shown in the figure) is provided in front of the touchscreen 4, the light grating is electrically connected to the PLC, and the PLC is also electrically connected to a buzzer 12. A protective cover is provided behind the touchscreen 4. The safety light grating in front of the operator and the protective cover behind the press enhance the safety protection level. This arrangement prevents accidental contact by the operator, thus preventing personal injury or mechanical damage and achieving an improved safety protection level.

[0031] The PLC solidifies the pressure holding time parameter, effectively eliminating human error and ensuring that each pressing operation reaches the designated position accurately, thereby guaranteeing product quality and production stability, and ultimately improving overall operational efficiency.

[0032] The PLC working process in this technical solution:

[0033] The PLC working process is as follows:

[0034] Initial position: The downward cylinder 6 is in the upper position, the left and right movement cylinder is in the right position (the cylinder that enables left and right movement can be one that is already on the operating table, or it can be installed separately in this application. If it is not necessary, it can be left unadded), the grating is in an unobstructed state, the 26-pin aviation plug is automatically identified by the wire number as one of the tooling types (A / B / C), and the corresponding program is found through the A type instruction. The touch screen 4 displays the currently used A type tooling.

[0035] The operator places the workpiece to be processed into the machine and presses the start button with both hands. The solenoid valve drives cylinder 6 (01) to press down until the lower limit sensor lights up, and the program starts the pressure holding timer (the time can be set by the operator via touch screen 4). After the time is up, cylinder 6 returns to its original position, and cylinder 6 (02) moves to the left until the left limit sensor lights up. After 0.5 seconds, cylinder 6 (01) presses down again until the lower limit sensor lights up, stopping the pressure holding timer. After the time is up, cylinder 6 (01) returns to its original position, and after 0.5 seconds, cylinder 6 (02) moves to its original position. The machine returns to its original position, the workpiece is removed, and the machine waits for the next cycle.

[0036] Abnormal reset / emergency stop:

[0037] If the light grid is accidentally touched during the pressing process, the machine will stop immediately and sound an alarm. If pressing the start buttons again at this time does not produce any response and the alarm continues, the machine must be reset and restarted. If the entire circuit has no output after the emergency stop is pressed, it must be reset before normal use can resume.

[0038] The embodiments described herein are preferred embodiments of this utility model and are not intended to limit the scope of protection of this utility model. Therefore, all equivalent changes made to the structure, shape, and principle of this utility model should be included within the scope of protection of this utility model.
